MACHINE FOR ROLLING TIRES.

SPECIFICATION forming part of Letters Patent No. 748,594, dated January 5, 1904, Application filed Tune 13, 1903- Sarial No. 161.379. (N0 model.)

To all whom it may concern.-

Beit known that I, PETER EYERMANN,a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and justment to admit of operating upon the tire.

as it is reduced and a pressure-roll mounted in a carrier which is provided with positivelyacting adjusting mechanism to hold the pressure-roll up against the inside of the tire as it is being formed by the action of the shaping-rolls.

In the accom panying drawings, illustrating my invention, in the two figures of which like parts are similarly designated, Figure 1 is a. top plan View of sufficient of a tire-rolling machine to show the application of my invention. of one of the shaping-rolls and its slide, ona

larger scale.

The frame 1 may be of any approved construction to receive the mechanism.

and these slides are connected to be simul-.

taneously moved toward and from each other 8 on a shaft 9, mounted in a carrier-block 10, which is pivoted at 11 to a cross-head 12, the cross-head and pivot 11 being suitably sup- Fig. 2 is a cross-sectional elevation.

Slides 2 are arranged in suitable ways 3 inthe frame,

mounted upon shafts l5, erected upon the frame. The longer arms of said elbow-levers are separately connected by links 16 with slide-blocks 17, mounted in ways 18 on the frame and connected bya right and left hand screw 19, also supported on frame 1 and adapted to be power-driven to cause the slide-blocks 17 to approach and recede,asindicated by dotted and full'lines, respectively. As the slideblocks 17 approach the pressure'roll is moved away from the shaping-rolls, as indicated by dotted lines, to ad mitof the removal of a finished tire and the placing of a tire-blank in position to be rolled, and as they recede the pressure-roll is moved toward the shapingrolls to hold the blank against the shapingrolls to cause them to impress their profile upon the tire. The active work of shaping is effected between the pressure-roll and the stationary roll 6, and the rolls 5 serve as tire sup ports and guides.

The whole mechanical arrangement for setting up the pressure-roll is behind and away from the tire, thereby permitting the introduction and removal of the work by simple adjustments of the parts without having to remove any of such parts. The right and left hand screws admit of the use of auxiliary electrical machines for moving them, and, further, since each of these screws is an integer they themselves sustain the load and it is taken 05 their bearings, so that the machine-frame is not weakened and there is no need for heavy or reinforced hearings or means to take up end thrust.

What I claim is v 1. In a machine for rolling tires, shapingrolls, a pressure-roll, and acarrierfor said pressure-roll, combined with a right andleft hand screw, slide-blocks on said screw, and connections between said slide-blocks and said carrier.

2. In a machine for rolling tires, shapingrolls, a pressure-roll, and a carrier for said pressure-roll, combined with a right and left hand screw, slide-blocks on said screw, elbowhead on the carrier, and links connecting the levers connected to said slide-blocks, and elbow-levers and cross-head. 10 links connecting the levers and carrier. In testimony whereof I have hereunto set 3. In a machine for rolling tires, shapingmy hand this 12th day of June, A. D. 1903. 5 rolls, a pressure-r011, and a carrier for said PETER EYERMANN.
